T 0 It whom it may concern:

Be it known that I, JAMEs R. HARRISON, a citizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, haveinvented certain new and useful Improvements in Vehicle-VVeighers; and Ido hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

This invention. has reference to weighing devices which are mounted onvehicles and adapted to weigh the'loa-d carried by the vehicle.

The object of my invention is to provide siin )lo and efficient means,which can be easily and readily applied to any ordinary vehicle, forweighing the load which it carries, and in furtherance of this objectthis invention presents many features of improvement over the vehicleweigher for which I tiled application for Letters Patent Dec. 30, 1905,Serial No. 294,014..

Referring to the accompanying drawings, which are made a parthereof, andin which similar characters of reference indicate similar parts in theseveral views, Figure 1 is a side view of a wagon with my weighingdevice applied thereto, showing the parts in their positions ofoperation, portions of the wagon wheels being broken away to give anunobstructed view of the parts of the weighing device; Fig. 2, a topview of the wagon of Fig. 1, portions of the wagon bed being broken awayto show parts of the weighing device on the bolsters; Fig. 3, a verticalcross sectional view, somewhat enlarged, on the line 33 of Fig. 1,looking in the direction indicatedby the arrow: Fig. 4, an enlarged topview of one of the lifting members of the weighing device, in itsposition of operation, showing adjacent parts on the bolster; Fig. 5, asectional view on the line 5-5 of Fig. 4, looking in the directionindicated by the arrow; Fig. 6, a view similar to Fig. 5, showing theparts thereof in the positions they assume when not in operation; F ig.7 a vertical sectional view on the line 7-7 of Fig. 3; Fig. 8 shows theextension for lengthening the lifting levers, and the manner ofconnecting the same thereto; Fig. 9 is a longitudinal sectional view onthe line 9-9 of Fig. 8, looking in the direction indicated by the arrowFig.10 an enlarged view of the joint of the rear lever of Fig. 1 Fig. 11is a vertical sectional view, somewhat enlarged, of the scale mechanism,on the line 1111 of Fig. 1, looking in the direction indicated by thearrow. Fig. 12 is a fragmentary view looking at the inner side of thebolster showing the parts of the Weighing device thereon, shown in Figs.4 and 5; Fig. 13 an enlarged side view of that end of the scale beam towhich the weight of the load is applied showing the manner of supportingsame on the side of the wagon. bed; and Fig. 14 is a sectional View ofthe transverse piece 51 to which the ends of the lifting levers areattached, the said view being taken just inside the upturned portion 52looking inwardly.

Inthe drawings, which show the application of my invention to anordinary wagon, 1 is the wagon bed, which'is supported on the bolsters 2and held thereon against lateral displacement by the standards 3 whichare provided at each end of the bolsters. The bolsters are connected andmounted on the running gear of the wagon in the usual manner, and on thetop of each bolster, intermediate of the standards is a strip orsuperstructure 4., upon which the wagon bed is supported in its normalposition, said. strip being designed to hold the wagon bed above the topof'the bolster for purposes hereinafter mentioned. This strip orsuper-structure is arranged to be removable from its position on thebolster, and each end is incased in the upper and lower plates 5 and 6respectively, both of which are provided with t e matching'notches orcut away places 7 adapted to straddle the standards 3 and hold the stripor super-structure in place on the bolster.

At the inner side of the bolsters and at each end of the strip orsuperstructure 4, the upper plate 5 and the strip 4 are cut away, as at8, above the lower late 6 to receive the hooked extremity 9 of thelifting members 10 and 11, which said hooked parts are formed by thedownwardly.projecting knife edge bearing 12 on each lifting member,which said knife edge bearing is adapted to bear on the grooved bearing12 which sits in the cut away place in the strip 4 on the plate 6, andthe strip or superstructure 4 is provided and is of suitable thicknessto'hold the wagon bed sufficiently abovethe bolster to permit freeoperation of the lifting members on the bolsters. The lifting -memberssubjected if it at 10 and 11, when not in operation, drop down againstthe side of the bolster as shown in Fig. 6, and when in such positionthe knife edge of the lifting member does not bear directly on thebearing member and is prevented from the wear to which it would be alltimes rested directly on the said edge. The raised edge 13 on the lowerplate 6 holds the bearing member 12 in place and said bearing member maybe riveted or otherwise secured to the late 6. There is a stud 14projecting laterally from each lifting member adjacent the knife edge,which said stud is embraced by the guard 15, which is preferablyintegral with the lower or bearing plate 6, extends upwardly and has thescrew 15 passing therethrough and screwed into the upper casting 5- asshown, to effectively prevent accidental displacement of the liftingmember from its position on the bearing plate 6. .The sides of the saidbearing plate, except. where cut away to allow admission of the hookedend of the lifting member, extendupwardly to the top plate 5 which reststhereon, and said lates 5 and 6 are preferably riveted together throughthe strip 4, as at 16, or otherwise rigidly fastened together and to thestrip 4. The upper plate 5 is provided at its outer edge adjacent thestandard with an upwardly extending portion 17 which lies against thestandard and has the inner face inclined downwardly as at 18, so as towedge the wagon bed away from the standard when at rest on the strip 4.

As above suggested, there is a pair oflifting members on each bolster,on the inner side thereof, one adjacent each standard, which have theirknife edge extremities 12 adapted to bear on the bearing members 12 onthe bearing plate 6, and thesaid lifting members are provided with thehub portions 19 which extend laterally from the body part thereofand arearranged some distance away from the knife edge terminals of the saidlifting members. These hub portions 19 on each pair of lifting membersextend inwardly toward one another and are bored to receive a largeshaft 20 which extends parallel with the bolster upon which the liftingmembers are mounted, and upon the ends of said shaft the lifting membersare secured and keyed, as at- 21, or otherwise secured so as to be heldexactly in line on the shaft and be correspondingly and simultaneouslymovable.

The laterally projecting hub portions 19, above mentioned, are eachfurnished on the upper part with a knife edge bearing 22 so arranged, asis also the knife edge 12 that when the lifting members are moved ontheir bearing edges 12 so that the vertex of bearing edge 12 and thevertex of bearing edge 22 lie in a horizontal plane, the said knife edgebearings will be perpendicular to said lane bisecting said knife edgebearings wi said horizontal plane.

The knife edge bearings 22 are adapted in the inoperative position ofthe lifting members, shown in Fig; 6, to be disengaged to prevent wearthereof, but are arranged so that when swung on their knife edgeterminals to come into contact with bearing members 22 on the wagon bed,and in the further movement thereof to raise the wagon bed off thestrips 4 so that when the vertices of the bearings 12 and 22 are broughtinto the same horizontal lane, the wagon bed is raised entirely free ffom the superstructure 4, and the wedge members 1.7 thereof.

As is apparent, the bearing edges 22 will contact with the bearingmembers on the bottom of the wagon bed at the sides thereof. and thereis a transverse strip 23 on the.bot tom of the wagon bed just insideeach bolster, which in the normal lowered position of the wagon bed liesalongside the bolster and serves to prevent longitudinal displacement ofthe wagon bed, and in the elevated position of the wagon bed moves clearof the bolster. These strips. extend from side to side of the wagon bed,and. are provided at each end above the lifting members 10 and 11 withthe plate 24, (shown in dotted lines in Fig. 4) which has the bearingmembers 22 integral therewith or separate and secured thereto which theknife edges 22 of the lifting members engage in raising the wagon bed,and said plates together with the strips 23 are cut away or notched asshown by dotted lines at 25, Fig. 4. to provide room for the operationof the hooked end of the lifting members.

The bearing members 22 shown in the drawings, and groove incline to thegroove so that as the knife edge 22 of the lifting member is raised itwill be forced into the groove and the grooved member 12 which theterminal knife edge of the lifting member engages is furnished so thatwhen the wagon bed is raised it will be held so that the transversestrip 23 and the transverse strip 23 are prevented from rubbingagainst'the bolster or strip 4 thereon. Theplates 24 are furtherprovided with upwardly 26 which lie against the sides of the wagon bedand are fastened thereto forv securing the plates and strips 23 morefirmly to the wagon bed, and to hold the sides of the wagon bed adjacentthe standards from spreading. For

further holding the sides of the wagon bed from spreading and forsupporting the wagon bed, when suspended, from settling or saggingintermediate of the bearing plates 24, there is provided a truss rod 27which is bowed beneath the transverse strip 23 and has the ends thereofextending angularly through the ends of the strips above the beararegrooved as the sides of the.

extending portions ing plates and protruding through openings intheupwardly extending portions 26 of the plates 24. Both of the protrudingends of this truss rod are threaded and provided with nuts 28 which arescrewed thereon against the upwardly extending part 26 of the bearingplates 24 for drawing and holding the said truss rod 27 taut. Betweenthe central bowed portion of the truss rod 27 and the strip 23 is afiller or brace 29, the upper face of which lies against the strip 23,and the lower edge of which conforms to the bowed shape of the truss rodas shown in Fig. 3, to properly distribute the support of the truss rodevenly throughout the width of the wagon bed.

To reduce the friction of the wagon bed against the standards 3, in theoperation of raising and weighing the load each standard is providedwith a pair of anti-friction rollers 30. These rollers are carried onbolts which pass through the standards, and are arranged on oppositesides thereof, one near the top of the standard and the other near thebottom, and extend beyond the plane of the inner face of the standard soas to bear against the plates 31 on the side of the wagon bed when thesides of the wagon bed are forced toward the standards.

The scale mechanism for indicating the weight of the load is mounted onone side of the wagon, and the lifting members 10 on that side of thewagon are provided with longitudinally extended parts 32 to which thelifting levers 33 and 34 are adapted to be attached for operating thelifting members for raising and holding the wagon bed in suspension. Thelifting members 11 on the opposite side of the wagon from the scalemechanism are operated through the shafts 20 from the lifting members 10and consequently are not provided with the extensions for attaching thelifting levers.

The levers 33 and 34 are removably connected with the extensions 32 ofthe lifting members 10, so that they may be readily and quickly placedin position when the weighing device is to be used, and quickly removedwhen through using, and for this purpose the extended part 32 isprovided with the laterally extending lugs 35 and 36 diagonally arrangedon the outer face thereof as shown so as to grip the lever wheninserted. therebetween and. moved upward, and said lugs have lips 37which overlie the lever when in position and hold it against theextended part 32. The keys 21. extend out beyond the face of theextended portion 32 a short distance, or other means may be provided, tolimit the insertion of the levers 33 and 34 between the lugs 35 and 36.

The levers 33 and 34 when in the initial position extend. substantiallydownward, an d in moving the lifting members 10 and 1] to raise thewagon bed describe a consider- Y able arc, so as to bring the verticesof the bearings 12 and 22 into the same horizontal l plane, and thelevers 33 and 34 are so conj nected with the lifting members 10 thatwhen the bearings 12 and 22 are in the position above indicated, thesaid levers extend horizontally. When in this position the free ends ofthe lifting levers are connected 1 with the scale mechanism on the sideof the I wagon for holding the load in suspension and I weighing theload. This scale mechanism j consists of the graduated scale beam 38which has the laterally projecting V-shaped or knife edge bearings 39near the end thereof at which the weight is applied, which said earingsengage the loops or eyes of the U- shaped link or clevis 40. This linkor clevis j 40 hooks onto the bracket 41 on the side of j the wagon bedso as to be easily removed. The long arm of the scale beam is graduatedl and has the weight 42 slidable thereon and j the pendent weights 43 atthe end, and said I end extends into the loop 44 on the side of I thewagon bed scale beam.

The reverse end of the scale beam, to which the weight of the load isapplied, is provided with a block 45 which slides lengthwise of thescale beam on the parallel rods 46 to adjust the leverage which the loadexerts l on the scale mechanism, and said block may I be accuratelyadjusted by means -of the 1 to limit the oscillation of the.

threaded member 47 which is mounted on the scale beam and has a threadedconnection with a portion of the block 45. When properly adjusted thesaid block is locked in l place by tightening the bolts 48which clampthe block immovably on the rods 46. This 1 block has laterally extendinginverted V- shaped knife edge bearings which carry the clevis 49, towhich is attached the link 50, to which the lifting levers 33 and 34 areattached when the load is to be weighed. The link 50 hooks on the clevis49 as shown and j is provided on its lower end with a trans- 1 versepiece 51. This transverse piece 51 is knife edged at each side of therod or link 50 I on the upper edge and supports the ends of the liftinglevers 33 and 34 thereon, one on each side of the rod 50, and has theupturned portions 52 at the outer ends of the said E knife edgedportions to keep the levers from slipping off the knife edged portions.The I transverse piece 51 has a threaded connection with the link or rod50 so as to be moved nearer or farther from the scale beam so that itcan be adjusted to hold the lifting levers 33 horizontal position.

and 34 in a perfectly As is apparent the wagon bed may vary in weight attimes from various causes, for instance when wet, or when it has beenrepaired, or when side boards have been put on, hence it is necessary toprovide means for adjusting'the scale mechanism to compensate for thevariations in weight of the wagon bed or other frame which carries theload. This means consists of the weighted bar 53 which is carried by thescale beam and is slidable lengthwise thereof through a tubular opening54 therein. By adjusting this rod lengthwise in said tubular opening 54,the scale beam may be brought to a perfect balance. It is evident thatthe wagon bed will seldom vary in weight consequently when the rod orbar 53 has been adjusted there is little need to change it. However,this rod is made detachable from the scale beam so that it may beremoved from the scale beam when the scale mechanism is taken off thewagon to reduce the .length thereof, and for the purpose of enabling theoperator to easily and quickly insert the said rod or bar 53 at theproper adjustment, the collar 55 is provided on the rod, which saidcollar may be adjusted and set on the rod to contact with the end of thetubular opening when in the proper osition of adjustment.

The bolsters of t e wagon are not always the same distance apart, forinstance, when used with a hay-rack the bolsters are considerablyfarther apart than when used with the ordinary wagon bed. The levers 33and 34 are made of the length required for use with an ordinary wagonbed, and for adapting the weighing mechanism for any spacing of thebolsters an extension'56 is provided for each of the levers 33 and .34,and the scale block 45 is made adjustable as hereinbefore specified tocompensate. for the in: creased length of the levers. These extensionsare designed to extend in line with the levers and to be easily andreadily attached and detached therefrom, and for this purpose areprovided with a pair ofsuitably distanced, laterally projecting pins 57with heads on the outer ends thereof, which are adapted to engagesimilarly distanced slots 58 in the ends of the lifting levers. TheWidth of the slots 58 is the same as the diameter of the stem of thepins, and the ends of the said slots are enlarged as at 59 to permitinsertion therethrough of the heads. of the pins 57. To attach theextensions to the lifting levers the pins 57 are inserted through theopenings 59 and the extensions drawn forward until the stems of the pinslie in the opposite ends of the slots 58' from the enlarged openings 59,in which position the heads of the pins lie against the edge of theslots and hold the extensions against the levers. For adjusting theblock 45 on the scale to accommodate the increased length. of the levers33 and is placed in position, a known wei ht placed in the wagon bed orother load carrying frame, and the block 45 adjusted and set at suchposition in which the scale mechanism accurately registers the weight. v

As shown in the drawings Figs. 1 and 2, some wagons have the brake beamextending 34, the-scale lTlBCllELIllSIIL laterally from the wagon aconsiderable distance below the bottom of the wagon bed, and in suchcaseit will be necessary for the rear lever 34 to be constructed so that itcan be moved past the brake beam 60. This is effected by jointing thelever as at 61, so that the part 62 thereof may be swun on the art 63 onthe pin 61 to pass the bra e beam.

rovision is made for locking the arts 62 and 63 together in line,consisting o the slot 64 in the part 63, the notch 65 in the end of thepart 62, and the bolt or rivet 66 adapted to slide in the slot 64 forengaging the notch 65. When it is desired to move the lever 34 past thebrake beam 60 the bolt or rivet 66 is moved to the end of the slot 64out of engagement with the notch 65 leaving the part 62 free to move onthe pivot 61. After passing the brake beam, the parts are swung intoline and the bolt or rivet 66 moved to the opposite end of the slot 64into engagement with gether.

From the foregoing it is apparent that in the inoperative position ofthe weighing mechanism the only parts that are on the wagon are thebracket 41, the friction rollers 30, and the lifting members 10 and 11together with their connecting shafts 20. The lifting members and shaftsare then dropped down against the side of the bolster upon which theyare mounted, the extensions 32 being of such length that they donotinterfere with the movement of the bolsters on their supporting part.

To weigh the load, the scale mechanism is hooked on the bracket 41, andthe lifting levers 33 and 34 attached to the. extensions 32 of thelifting members 10, raised to a horizontal position and the ends thereofsupported on the transverse piece 51 of the scale mechanism, when theweight of the load may be ascertained as is any ordinary scalemechanism.
